Creative Commons Catalog vs Shields

Creative Commons's search catalog was handed off to WordPress.org and relaunched as Openverse; the old `api.creativecommons.engineering` host now 301-redirects to the current `api.openverse.org`. A live unauthenticated GET against `api.openverse.org/v1/images/` returned a 200 JSON result set with `Access-Control-Allow-Origin: *`, confirming keyless anonymous search still works today (rate-limited to 200 requests/day per IP), with an optional `/v1/auth_tokens/register/` OAuth2 client-registration endpoint (confirmed live, returning a 400 validation error rather than 404) for higher limits. The catalog itself and every indexed work are free to use under their respective open licenses.

Shields.io serves status badges as SVG by default from `img.shields.io`, with `.png` requests 301-redirected to a raster-conversion host and a `.json` suffix returning the same badge's label/value/color as plain JSON — all three confirmed live. A live unauthenticated GET returned `Access-Control-Allow-Origin: *` on every format, resolving cors "unknown" to "yes". Free, open-source, and keyless, funded by sponsorships rather than a paid tier.
